Development of automatic methods for agricultural mapping and monitoring using remotely sensed imagery has been an important research problem. We describe algorithms that exploit the spectral, textural and object shape information using hierarchical feature extraction and decision making steps for automatic mapping of linear strips of woody vegetation in very high-resolution imagery. First, combinations of multispectral values and multi-scale Gabor and entropy texture features are used for training pixel level statistical classifiers for characterizing individual trees and tree groups with respect to their surroundings. Then, decisions based on object level texture features and morphological shape analysis provide the final detection of woody vegetation having a linear structure. Experiments on QuickBird imagery from different sites show that the proposed algorithms provide good localization of linear strips of woody vegetation in different landscapes.

ABSOLUTE RADIOMETRIC CALIBRATION OF THE GOKTURK-2 SATELLITE SENSOR USING TUZ GOLU (LANDNET SITE) FROM NDVI PERSPECTIVE Sakarya, Ufuk; Demirhan, Ismail Hakki; Deveci, Husne Seda; Teke, Mustafa; Demirkesen, Can; Kupcu, Ramazan; Oztoprak, A. Feray; Efendioglu, Mehmet; Simsek, F. Fehmi; Berke, Erdinc; Gurbuz, Sevgi Zubeyde (2016-07-19) TOBITAK UZAY has conducted a research study on the use of space-based satellite resources for several aspects of agriculture. Especially, there are two precision agriculture related projects: HASSAS (Widespread application of sustainable precision agriculture practices in Southeastern Anatolia Project Region (GAP) Project) and AKTAR (Smart Agriculture Feasibility Project). The HASSAS project aims to study development of precision agriculture practice in GAP region. Multi-spectral satellite imagery and aeria...
Automatic multi-scale-segmentation of high spatial resolution satellite images using watersheds Şahin, Kerem; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2013) Useful information extraction from satellite images for the use of other higher level applications such as road network extraction and update, city planning etc. is a very important and active research area. It is seen that pixel-based techniques becomes insufficient for this task with increasing spatial resolution of satellite imaging sensors day by day. Therefore, the use of object-based techniques becomes indispensable and the segmentation method selection is very crucial for object-based techniques. In ...
An Evaluation of Land Use Land Cover (LULC) Classification for Urban Applications with Quickbird and WorldView2 Data Cavur, Mahmut; Nabdel, Leili; Kemeç, Serkan; Düzgün, Hafize Şebnem (2015-04-01) Monitoring and analysis of the land and rapid environmental change, leads to the use of Land Use and Land Cover (LULC) classification approaches from remote sensing data. The main focus of this aper is to illustrate the practical approach to analysis and mapping of land use and land cover features using high resolution satellite images. The study is carried out for two different places, Basel and Tel Aviv. For this purpose, Quickbird satellite imagery is used for Basel and WorldView2 imagery for Tel Aviv. T...
A new algorithm for automatic road network extraction in multispectral satellite images Karaman, Ersin; Çınar, Umut; Gedik, Ekin; Çetin, Yasemin; Halıcı, Uğur (2012-05-09) The aim of this study is to develop automatic road extraction algorithm in satellite images. As roads have different width and surface material characteristics in urban and rural areas, a modular approach for road extraction algorithm is desired. In this study, edge detection, segmentation, clustering and vegetation and land cover analyses are used. In order to combine the results of different methods, a score map based on segmentation analysis is constructed. Quantitative and visual results show that this ...
Geographic information systems (GIS) for the determination of inundation maps of Lake Mogan, Turkey Merzi, N; Aktas, MT (Informa UK Limited, 2000-09-01) The use of geographic information systems (GIS) allows for a very efficient analysis of spatial hydrologic data for water resources projects especially for water control studies. rn this respect, flood hydrographs for Mogan basin, Turkey for different durations and return periods are determined by using Soil Conservation Service (SCS) method. The basic parameter of the SCS method, curve number (CN), is evaluated by using GIS employing digital land use and hydrologic soil group data derived from analog maps....
